This invention relates to improvements in screen and storm sashmountings for windows. v

The main object of the invention is to provide a mounting or arrangementwhereby screen and storm sash may be initially in stalled andsubsequentlyremoved or replaced in a window entirely from the insidethereof, thus eliminating the use of ladders, scafl'olds '10 or the likeat the outside of the window.

Another object is to provide a mounting of this kind equally applicableto either wood or metal window frames.

Another object is to provide a mounting having simple and positivelocking means and which will require a minimumof alteration' in thewindow frame in the process of installing the sash. l 7

With these and other objects in view, the

v invention resides in-the novel construction and arrangement of partsas hereinafter fully set forth and claimed, reference being bad to theaccompanying drawings wherein Y F igure 1 1s a vertical section througha window frame of wood,"showing the lower screen or storm sashin theprocess of being mounted in place; i Figure-2 is a view similar toFigure 1, but

spectively the upper and lower screen .or storm sash. The sash BandC-comprise the usual sides or stiles 1, meeting rails 2'and'3, '65andtop and bottom rails Land 5, forming rectangular frames on or; inwhich the screen or storm covering is placed. I As thus formed,

the sash B and C are intended for mounting in the window frame Aoutwardly of the up- '70 per and lower window sash Gand 7 therein, thesaid sash B and C being'of such size as to close the opening in theframe A when the upper sash is disposed above and1in line with the lowersash. The meeting rails 2 and 3 are rabbeted at 8 to overlap and form atight joint as shown in Figure '2.

. In accordance with the present invention and in'preparing the windowframe A for the mounting of the sash B and 0, side and head so stops 9and 10 are secured to the frame A outwardly of the window sash 6 and 7and in the angle formed at the junction of the head and side casings 11and'the blind 'stops12 of the frame A.- These stops 9 and 10 arerabbeted along their inner corners as shown at 13 to receive thecomplementary rabbets 14 in' the stiles 1' and top rail 4 of the sash Band C, whereby a tight joint is provided between the said sash andstopsand whereby PATENT OFFICE 831d. sash a I are held against outwardmovement in the frame A. It will be noted that the stops 9 and 10 extendinward beyond the plane of the inner faces of the blind stops 12, sothat the allowable width of the sash Band C is less than the distancebetween the blind stops at the sides of the window frame, this for thepurpose of allowing the said sash to clear the blind stops and otherparts of the window without coming in contact with and marring the same.Approximately midway between the center and lower ends of theside stops9, the rabbeted corners 13 thereof are mortised out a short distance toprovide recesses 15 in which the lower sash locks 16 are mounted,

these locks being formed of attaching plates 17 provided with inturnedlugs or cars 18 along their margins as shown in Figure 5.

The locks aresecured in the: recesses 15'by screws 19 passed throughsaid plates 17 the lugs 18 being thus spaced outward'with respect totheangle formed by the rabbets13.

substantially vertical position:

At their upper ends the lugs 18 are bent outwardly at right angles} asdesignated at 20.

The lower sash C is provided with looking pins 21 driven in the outerlateral margins of its stiles 1 and projecting a short distancetherefrom. To mount the lower screen sash C in the window frame A, thelower window sash 7 is raised as far as possible and the sash C is thenpassed through the opening thus formed. As the upper end of the sash Cstrikesthe "side stops 9, the sash is upward'until its lower end clearsthe window sill at which t me the saidlower endmay then beswung outwardin the frame to a 'ing'pi'ns 21 come into line with the outwardly turnedfends 20 of the lock lugs 18, the sash 'C is p'ushedoutward in thewindow frame, causing said pins 21 to pass over the said lug.

The screen sash may'then be lowered untilits bottom rail 5 meets thewindow sill, the

' m'e'eting rail '55 upper end of side and head screen sash C is thusrestrained'against up- -ward movement'while the upper sash B is inplace, and by locking said upper sash against an inward movement at itsupper end, a rigid and safe screen is provided. This locking of theupperscreen sash B is accomplished by ailatch 22 pivoted at 23 in a slot24 provided verticallythrough the top rail 4; of the sash the slot 25.

pushed angularlyf As the lockand adapted to enter a slot 25 cut in thehead i stop 10 as clearly shown in Figures 6 and7.

The latch 22 is operable from the interior of thewindow frame by ahandle 26 and of course serves to prevent the aforesaid inward B whenengaged with swinging of the sash In Figures 8 to 11 inclusive, themounting of the sash Band C in a metal window frame A is shown. In thiscase the side and head stops 9 and 10 are formed of angle irons 9a and10a secured to the frame A by screws 27' and have their inwardlyextending webs 28 disposed outwardly with respect to the windowframewhereby the sash B and G will I enter into the open angles of the saidstops 7 and will be restrained against outward movement by the said webs28 in. a manner similar to the rabbeted" stops 9 and 10. Approximatelymidway between the center and lower.

ends of the "side angle'irons 9a,lpins 29 are threaded in the webs 30 ofthe saidirons and are extended inwardly therefrom. The stiles 1 of thelower sash C areprovided with lock- 7 ing plates 31 on their outerfaces, which plates are provided with slots 32 opening at their lowerends at the outermost edges of the said plates whereby to receive andhold the said pins29 when the lower sash is mounted in the window frame.The actionof mounting both the sash B and C is identicalcwith that firstdescribed with reference to the window frame A, and it is not thoughtthat further description is necessary. To look the upper "i screen sashBin place, a latch 22a identical in'mounting'and operation to the latch22, is provided and is adapted to enter and lockingly engage a slot 25aprovided in the upper angle iron 10a as'shown' in Fi ure 9.

From the foregoing lt'wlll e evident that the screen or storm sash maybe readily rior thereof and may be as readily removed when necessary,the-removal being accomplished by first unlocking and removing the uppersash and then raising and removing-the lower sash as will be readilyunderstood. The performance of'these operations entire ly from withinthe window or room'has manifold advantages particularly in cases wherethe windowsare located a considerable distance above the ground orstreet level. The use of two sash for each window is of advantage in thestoring or transportation of the sash, especiallywhen the windows arelarge.

7 hile I have herein set forth a certain preferred embodiment of myinvention, it is understood that I mayvary from the same in minorstructural details, so as best to construct a practical device for thepurposes intended, notdeparting from the spirit of the invention andwithin the scope of the appended claim.

I claim:
